Zirconium-89-girentuximab PET/CT Imaging in Renal Cell Carcinoma

Thirty patients (suspected of ccRCC) will be included in whom conventional diagnostics are inconclusive. During a multidisciplinary team (MDT) the hypothetical next step in the clinical process will be noted. Subsequently, in these patients a Zirconium-89-girentuximab PET/CT will be performed 4-5 days after single intravenous injection of 5 mg Zirconium-89-girentuximab (37 MBq). The results of the PET/CT will be discussed during the MDT and will be used to decide what the next step in the clinical process will be. This step will be compared with the hypothetical next step from the MDT before the scan. Whether or not the PET/CT scan had impact on clinical decision making will be assessed for each individual patient.
